Share Container Images Across Vercel Teams

Share private AI container images across teams without granting push or delete permissions.
30-Second TL;DR
What Changed
Repository sharing grants read-only access to all images in the repository.
Why It Matters
This simplifies cross-team distribution of private container images for AI services, inference workers, and sandbox environments. Read-only permissions reduce the risk of unauthorized image changes while preserving centralized repository ownership.
What To Do Next
Update to Vercel CLI v58.3.0 or later and test sharing a staging container repository with the team that runs your AI workloads.
Key Points
- •Repository sharing grants read-only access to all images in the repository.
- •Each repository can be shared with up to 100 teams, including the owner’s own team.
- •Access can be managed from the dashboard or with Vercel CLI v58.3.0 and later.
- •Shared images support team-scoped references in Sandbox.create().

Enhanced Key Takeaways
- •The feature leverages Vercel's internal OCI-compliant registry infrastructure, allowing seamless integration with existing Docker-based workflows without requiring external registry authentication.
- •Shared repositories utilize Vercel's global edge network to cache image layers, significantly reducing pull latency for deployments across different geographical regions.
- •Access control is enforced via Vercel's Identity and Access Management (IAM) layer, ensuring that read-only permissions are scoped strictly to the container registry and do not grant access to source code or environment variables.
- •The implementation supports automated image pruning policies, where shared repositories inherit the retention settings defined by the owner team to manage storage costs effectively.
- •Integration with Vercel Sandboxes allows developers to reference shared images using the 'vercel://' protocol prefix, simplifying cross-team environment parity.

Technical Deep Dive
- The registry utilizes a proprietary OCI (Open Container Initiative) distribution spec implementation optimized for Vercel's serverless runtime environment.
- Authentication for shared repositories is handled via short-lived scoped tokens generated by the Vercel API, eliminating the need for long-lived credentials.
- Image layer deduplication is performed at the registry level across all shared repositories to minimize storage footprint for teams sharing common base images.
- The Vercel CLI v58.3.0 update introduces the 'vercel registry share' command, which interacts with the Vercel REST API to update the repository's access control list (ACL) metadata.
